The work was carried out to a high standard. Chris, Jordan and Conner were very efficient and worked hard. They tidied up after them and the job which included a lot of new pipework was carried out over 2 days. Nina in the office was very helpful and kept me informed at all times. Thank you all for doing such a good job.
